Kidney stones are one of the causes chronic kidney failure that can cause long-term complications. Kepok banana peel and yellow watermelon still rarely used as medicine. The high flavonoid potassium content in kepok function a stone remover improve function. preparation started with extraction peel. Then, contents extracts were tested. Nanoemulsions prepared by homogenization method at 15,200 rpm. Finally, nanoemulsion formula was evaluated. Nanoemulsion had size 246.9 nm PDI 0.618 . also contained flavonoids pH value 7 viscosity 2.70 cP. reduce creatinine levels there is no decrease ureum model rats. administration did not significantly affect levels, but decreased nonnanoemulsion intervention groups.

pH and Pectinase Dual-Responsive Zinc Oxide Core-Shell Nanopesticide: Efficient Control of Sclerotinia Disease and Reduction of Environmental Risks

Nanomaterials, Journal Year: 2024, Volume and Issue: 14(24), P. 2022 - 2022

Published: Dec. 16, 2024

Sclerotinia sclerotiorum is one of the fungi that cause plant diseases. It damages plants by secreting large amounts oxalic acid and cell wall-degrading enzymes. To meet this challenge, we designed a new pH/enzyme dual-responsive nanopesticide Pro@ZnO@Pectin (PZP). This uses zinc oxide (ZnO) as carrier prochloraz (Pro) encapsulated with pectin. When encountering released sclerotiorum, acidic environment promotes decomposition ZnO; at same time, pectinase produced can also decompose outer pectin layer PZP, thereby promoting effective release active ingredient. Experimental data showed PZP was able to achieve an efficient rate 57.25% 68.46% when added or under conditions, respectively. In addition, in vitro tests antifungal effect comparable commercial Pro (Pro SC) on market, its efficacy 1.40 times 1.32 original drug TC), Crucially, application significantly alleviated detrimental impacts wheat development. Soil wetting experiments have proved primarily remained soil, decreasing likelihood contaminating water sources reducing potential risks non-target organisms. Moreover, improved foliar wettability Pro, lowering contact angle 75.06°. Residue analyses indicated did not elevate residue levels tomato fruits compared conventional applications, indicating formulation does lead excessive pesticide buildup. summary, shows great promise for effectively managing while minimizing environmental impact.
